I tested 3 swabs on 3 different products and all swabs had a little bit of red around the base where the cotton connected to the wooden stick. The main part of the swabs that I rubbed against the metal items remained yellow (negative) but the little ring of red around the base of the cotton ball threw me off a bit. Maybe it's because of the adhesive that they used to adhere the cotton to the stick, could also be reactive with the chemicals.

I assume the lead test work. Nothing I tested actually changed colors to indicate there was lead present. It's really simple to use. The swab needs to be wet, then it must rub on the surface being tested for 20 seconds. Results would show within a minute.

This works really well. I was shocked by some things I discovered when I used it.

I needed to know if some specialty cups were safe to drink out of. This product revealed that there was no lead in the inside of the cup. I will be trying it on vintage glassware and I hope I get the same results.

Lead poisoning is less common in developed countries due to strict regulations, but it remains a risk in older homes and certain industrial settings. In the U.S., lead-based paint was banned in 1978, but lead particles from old paint chips or dust can still be inhaled or ingested, causing serious health issues like cognitive deficits and developmental delays, especially in children.These swabs use sodium rhodizonate, which changes color in the presence of heavy metals like lead, barium, antimony, and mercury. While sodium rhodizonate is often used to detect lead in gunshot residue, it’s also effective for testing metals, water pipes, plastic, vinyl, ceramic, glass, painted wood, and toys.The swabs are single-use and extremely easy to use. Just wet the sample area with a couple of drops of water, rub the swab on it for 20 seconds, and check the tip for any color change. If lead is present, the swab turns purple, indicating detectable levels of lead.At first, I thought lead was only a concern with painted surfaces like walls and windowsills, but you should also test old water pipes, faucets, imported cosmetics, vintage toys, jewelry, crystal dishware, and antiques. Cheap products from developing nations and certain retailers (like Shein and Temu) can still contain lead due to lax regulations. This might make you feel paranoid about lead exposure, but these swabs are affordable, quick, and easy to use. You don’t need to call in professionals to perform basic tests.I haven’t found any lead yet, but I’m planning to buy more swabs just to be safe. Better to be cautious than risk lead exposure.

I bought this to test jewelry as it is advertised for that. I got a positive test. I tested it against a control sample of copper and it tested positive. So they are completely useless on any metal surface.

Specifically wanted to test those 2 things and both came back positive. I knew the paint would have lead as it's pretty much a given but it's good to know that my PPE for scraping and repainting my wood windows is not for nothing.Solder had lead in it through the early 1980s. Most brass fittings also have lead in them. I wanted to check this as the plumbing in the house is a bit of spaghetti. It is positive, so that's good to know also.Tested a couple coffee mugs as I just learned they apparently may have lead in them, but they were negative. Tested my psyllium daily fiber powder as I also just learned that it also has may have lead in it. There's a class action against a major name brand but I use an off brand. Anyway that was negative but I highly doubt this is a sensitive enough test to pick up trace amounts. It says it tests down to 2mg/cm^2 which is kind of a lot. That's way too high to try to test your tap water with as those need to be much more sensitive.Easy to use and got results in less than 30 seconds. The entire swab doesn't turn purple on a positive, fyi. A helpful tip if you aren't sure is to fold up a paper towel and rest the swab on it so the liquid gets absorbed by it. You will absolutely see if there is any purple as it spreads out over the paper towel. Give it 30 mins and the stain will either be all yellow or yellow with clear lines of purple.
